Tail light bulbs

Im working with a 66 Dart here but this may help others with similar situations. As I work to get my car ready for its spring debut it was time to wire in the rear lights. Once that was done it was time for the bulbs. Here's where my learning experience starts!! .
My Dart has 4 tail lights across the back. The 2 outside in the rear fender are the Brake/turn/parking light and the inside lights are mounted in the trunk deck and are parking lights only.
Now before I go into my learning experience let me say that in 1973 I started working in my dads repair shop at the age of 14. In that era the most common bulbs for the rear of everything was the 1157 and the 1156. I installed them in cars for almost 15 years before I went to work in another field. And I mean they fit everything in front and rear lights!!
So last night I installed the brake/turn/parking bulbs using the 1157 bulbs. Then I put the 1156 in the inside parking lights. I put power to the car and pulled the light switch, walked around to the rear and looked at the lights. They were lit but the right bulb looked like a brake light, very bright. SO I replaced it with another 1156 only to have the same issue. Now I think I have a electrical problem but I decide to swap left from right. The brightness followed the bulb which eliminates wiring. I swapped that bright bulb out with 4 more 1156 bulbs only to find the same issue. So today I call NAPA and Jim at the counter (who spent many years at a Dodge dealership as a mechanic) siad maybe you need the 1141 bulb. I had never used one of that number bulb so I bought 2 of them. Went home and same issue. then I started looking at the bulbs only to discover the bulb that matched the outer parking light was not an 1156 but it was a 1094. I have never used one of those either so tomorrow I will be going back to NAPA to get a few of those.
Hoping that they will all be a dimmer matching light to the parking light side of the 1157 bulb.
See even at my old age I guess theres always something that can be learned!!
Here are pics of what I found as I started this light project. They are that bright it looks like brake lights! The last pic is using the LED 1156 with the LED 1157 bulbs. I was hoping they would work out better as I have had them for 3 years after being referred to them by a member here. DSCN1136.JPG DSCN1137.JPG DSCN1138.JPG
